ZXY2925 Power Isolation Transformer Audio 1:1+1 Permalloy Audio Transformer
1.Product Description
ZXY2925 Power Isolation Transformer Audio 1:1+1 Permalloy Audio Transformer is a high-performance transformer designed specifically for the audio field. It is made of Permalloy material, which has high magnetic permeability and low hysteresis loss characteristics, and can effectively reduce audio signal distortion and noise interference; The unique 1:1+1 winding design enables precise signal balance transmission and electrical isolation, eliminates ground loop interference, and significantly improves left and right channel separation and sound purity; Whether it is professional recording studio equipment, Hi Fi sound systems, or high-end broadcasting equipment, this transformer can present high fidelity and low background noise sound effects with excellent audio signal processing capabilities, providing stable and reliable signal transmission guarantee for audio equipment.
ZXY2925 Permalloy audio transformer with unique design and high quality materials, in the audio signal processing advantages, specific advantages are as follows:
1. High-fidelity sound transmission: the use of PoMo alloy material, its magnetic permeability is very high, can effectively reduce the hysteresis loss and eddy current loss, minimize the distortion of the audio signal to ensure that the sound original sound reproduction, for professional recording, Hi-Fi audio and other equipment to provide high-fidelity sound quality.
2. High-efficiency electrical isolation: 1:1+1 winding structure realizes excellent electrical isolation effect, which can completely eliminate ground loop interference and avoid current noise due to potential difference, making the audio signal pure and free of noise, and the separation of left and right channels is greatly improved to enhance the three-dimensional sense of sound.
3. Low noise performance: the low loss characteristics of Po Mo alloy, with precision winding process, effectively inhibit electromagnetic interference (EMI), reduce the noise floor generated by the transformer itself, in a quiet environment can also ensure the clarity and purity of the audio signal.
